your rear pinion angle... make sure to get a 2° drop, compared to the rear driveline angle. Triple measure.
Thanks! Since installing my Old Man Emu lift I have had a vibration in the back end, particularly at high RPMs - could that be due to a steep rear pinion angle? How do you control the driveline angle - lowering the Tcases, change the Tcase mounts, modify the axel/diff? How do you measure/set the angle to get it right?
